I compared the performance of X11 on two otherwise idle machines.
Hardware
========
Both have
identical mainboards (Aopen i915GMm-hfs),
identical memory and BIOS setup.
Both cpus are Intel Pentium M mobile (Dothan).
One runs at 1.86 Mhz, the other runs at 2.00 MHz
Software
=======
1.86 MHz system:
opensuse 11.2
X.Org X Server 1.6.5
Release Date: 2009-10-11
kernel 2.6.38.5
2.00 MHz system:
opensuse 11.4
X.Org X Server 1.10.99
git-tree, 2011-may-7
kernel 2.6.39-rc4-drm-intel-staging
x11perf results
===========
The first line always gives the test result of the 2.00 Mhz system with the current Xorg,
the second line gives the test result of the 1.86 MHz sytem with Xorg 1.6.5. Read a
few representative examples:
10000000 trep @ 0.0032 msec (309000.0/sec): Dot
40000000 trep @ 0.0006 msec (1650000.0/sec): Dot
45000 trep @ 0.5973 msec ( 1670.0/sec): 500x500 rectangle
100000 trep @ 0.4282 msec ( 2340.0/sec): 500x500 rectangle
2000000 reps @ 0.0034 msec (296000.0/sec): 1x1 stippled rectangle (8x8 stipple)
8000000 reps @ 0.0007 msec (1420000.0/sec): 1x1 stippled rectangle (8x8 stipple)
1500 trep @ 22.4602 msec ( 44.5/sec): 500x500 stippled rectangle (8x8 stipple)
3000 trep @ 9.2680 msec ( 108.0/sec): 500x500 stippled rectangle (8x8 stipple)
100000 trep @ 0.4043 msec ( 2470.0/sec): Fill 10x10 trapezoid
1000000 trep @ 0.0336 msec ( 29700.0/sec): Fill 10x10 trapezoid
The old X on the PC with the slower cpu is always significantly faster than the current git code,
very often more than 5 times as fast, and a number of test show 1.6.5 to be more than 12 times
faster than 1.10.99.
I did not use any special configuration options at compile time
1.10.99 was built using the following commands.
export PREFIX=/home/knut/local
export PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig
export PATH=$PREFIX/bin:$PATH
export ACLOCAL="aclocal -I $PREFIX/share/aclocal"
export LD_LIBRARY_PATH=$PREFIX/lib
export PYTHONPATH=$PREFIX/lib/python2.7/site-packages
util/modular/build.sh -g $PREFIX
Could anybody please explain why the old server is so much faster?
Are there any compile time or runtime options that could/should be used?
cu,
Knut

I'd start by suspecting differences in .config for the kernel between
the two, particularly since...

Dot dispatch is so completely CPU-dominated that I suspect you're simply
measuring CPU overhead somewhere else. For example, if one of those
kernels is built with spinlock debugging and the other isn't.

As a point of comparison, here are the similar results with master of all
the various trees on my 1.6GHz N450 (Atom+PineView) [so not strictly an
apples-to-apples comparison, your CPU is about 4-5x faster, but PNV is
about 3-4x faster than the 915GM (clock-for-clock)]:

Hmm. My suspicion was that this was GEM-related regressions (the overhead
of dynamic buffer manager and relocations) along with various
optimizations for the common cases affecting the software fallback
dominated benchmarks selected above. And whilst there may some element of
that behind the regression you're observing, I don't think that is the
whole story and Adam is right to suggest to check that the systems are
indeed configured identically (wrt to debug and optimisation options).

Yes, I made some mistakes during my first measurements.
Below find better results. They are made on the same machine,
with the same kernel, at the same speed, with the same x11perf
program, absolutely nothing changed.
I used x11perfcomp -ro and sorted the output, worst results for
the currrent git code first.
I think the numbers below are quite interesting ...

Something is still not quite right here. This should be mostly CPU bound,
and even my Atom gets 734k.
Can you check that (a) it is CPU bound and (b) the worst offenders
according to the system profiler of your choice (e.g. perf)?
Thanks for doing this investigation.

You don't mention whether the 2d driver varies; I assume it does at
least to the extent of rebuilding for new ABI. Or libdrm, although
that's really a 1% kind of thing.
> I think the numbers below are quite interesting ...
I still wager they're more about the environment than about the driver
proper, there's just too many weird things going on in your results. For
example:
> 198000.0 0.27 ShmPutImage 10x10 square
> 1570.0 0.46 ShmPutImage 500x500 square
> 21700.0 0.61 ShmPutImage 100x100 square
This is essentially a memcpy benchmark. Something has to be very wrong
for that much variation to happen, and my guess would be something like
failing to inline memcpy or pick sufficiently macho optimized versions.
I'd be interested to see what your CFLAGS from build.sh ended up being,
relative to what opensuse gives for 'rpm --eval "%{optflags}"'.
One cool thing you can do from memcpy benchmarks like this is
extrapolate a bandwidth number. Your fast numbers are (small tests to
big) 75.5, 828, and 1497 MB/s. Normally one expects some growth in those
numbers for bigger tests, but typically the jump from 10x10 to 100x100
is a bit larger than the jump from 100x100 to 500x500.
So that hints that small-work tests are being choked somehow. Recall
that x11perf does a 1-pixel GetImage periodically in order to guarantee
that results actually hit the framebuffer instead of just being queued
in the command stream, so round-trip performance with the X server does
actually matter. More than that, small-work requests (which take less
time) would be more strongly dominated by round-trip speed than
large-work requests. Given that:
> 15400.0 0.54 GetProperty
> 15500.0 0.54 QueryPointer
is very telling. Those requests do essentially no work, but they are
round-trips, and their throughput is thus bounded mostly by how long it
takes the scheduler to ping-pong between x11perf and the server. A
factor of ~2 drop would lead me to suspect something like one kernel
scheduling the processes on different cores, and the other both on the
same core; two processes splitting 1CPU time with maybe a little cache
warmth between them would intuitively be about half as fast as two
processes each with their own CPU.
Empirical evidence: On the Ironlake laptop on my desk (kernel
2.6.38.3-18.fc15), if I use taskset to bind the X server to CPU0,
running "x11perf -prop -pointer" bound to CPU0 gives:
300000 trep @ 0.0322 msec ( 31100.0/sec): QueryPointer
300000 trep @ 0.0321 msec ( 31200.0/sec): GetProperty
x11perf bound to CPU3 gives:
600000 trep @ 0.0193 msec ( 51900.0/sec): QueryPointer
600000 trep @ 0.0192 msec ( 52200.0/sec): GetProperty
And running it unbound (letting the scheduler decide) gives:
600000 trep @ 0.0198 msec ( 50600.0/sec): QueryPointer
600000 trep @ 0.0208 msec ( 48000.0/sec): GetProperty
I'd be curious to see how you fare with experimenting with taskset.
One set of results that's a little confusing, and thus probably in the
end most enlightening:

This _mostly_ makes sense. These are all just varying calls to
XCopyArea, which does not have a reply. The medium and large ops are
approximately identical before and after. The 0.8x results make sense in
the context of scheduling funniness for small-work requests. But the two
outliers are perplexing. I would guess that copywinwin10 got faster due
to some optimization surrounding buffer reuse or flush reduction (you're
always working on the same buffer, so you can do less work), and that
copypixpix10 is operating wholly in host memory for some reason and
therefore hitting the same kind of memcpy issue as in your ShmPutImage
results.
I'll also note that the paths where you're losing hardest are, in the
majority, things that the driver makes no attempt to accelerate
(anything with the word "tiled" or "stippled" involved, for example). I
would tend to chalk that up to something like gcc -O0 before anything
else since you're primarily measuring the efficiency of the software
renderer. I'm actually pretty pleased with the results you've shown, 10%
or better speedup for basically all text ops, about half of window
management ops, and almost all window exposure ops.

As I do have only a few minutes now, a few comments:
1: The complete trees are compared, all modules/libraries are either old or new. No debug-versions.
2: Speculating about cores is definitely wrong -- the Pentium M Dothan definitely is a single core cpu.
3. There often is a "choked most" (1) -- "choked least" (10) -- "choked a bit more again" (100,500)
result:
1450000.0 0.50 1x1 stippled rectangle (8x8 stipple)
134000.0 1.11 10x10 stippled rectangle (8x8 stipple)
2540.0 1.05 100x100 stippled rectangle (8x8 stipple)
110.0 0.95 500x500 stippled rectangle (8x8 stipple)
Heavy per call impact of factor A on those small requests, light impact of a factor B with growing numbers?
A = compiler / library overhead?
Yes, there is

but we also see
8150000.0 1.21 X protocol NoOperation
4. No, it's not the kernel. I did
a) boot
b) x11perf on old X
c) x11perf on new X
d) reboot
e) x11perf on new X
f) x11perf on old X
and saw only very marginal differences between those two runs.
5. Yes, I do agree to that:

734k would be nice ;-)
With current git Xorg its 10300 reps at 800 MHz and 16300 reps at 2000 MHz.
Increasing cpu clock by a factor of 2.5 increases reps by a factor of 1.58.

Please do something like 'perf record -f -g -a x11perf -d :0 -worect10;
perf report | head -150' and paste the output.

Oh, damage. A compositing WM? If you turn off compositing, do you see
similar performance levels to xorg-1.6?

That makes difference .... 16.300 reps speed up to 1.280.000 reps ... 78.5 times faster.
I think I will rerun the tests.

NoOp isn't a round trip, it does not generate a reply. That test
measures how fast the X server can zip around its own main loop, not how
fast it can interact with clients.

If "Composite" is disabled, the current X scores much better than the 1.6.5 server
in most cases. But there are a few exceptions ... for the worst of those cases, I
also attached a perf log.
